Just worked this out - Starship would need 4 Super Heavys as strap-on boosters to do a Mars mission in one launch
I was curious about this, so I set out to figure it out:
- A regular Starship/Super Heavy combo, as it currently stands, has 5000t mass and can go into LEO
- LEO to Mars requires ~3.7km/s of delta-v
- A single Super Heavy (the current iteration of it has a dry mass of 275t, a wet mass of 3675t, and an Isp of 327
- As such, n boosters would have to impart 3700m/s of delta-v to a 5000t payload (the Starship/Super Heavy core), to give it enough additional delta-v to reach Mars in a single launch
- Rocket equation: 327*9.81*ln( (5000+3675n)/(5000+275n) ) = 3700
- Rearrange: 5000+3675n = 5000*e^(3700/(327*9.81)) + 275n*e^(3700/(327*9.81))
- Rearrange again: 3675n - 275n*e^(3700/(327*9.81)) = 5000*e^(3700/(327*9.81)) - 5000
- Factor out n: n = (5000*e^(3700/(327*9.81)) - 5000) / (3675-275*e^(3700/(327*9.81)))
- Calculate: n = 3.868
- Since you can't have 0.868 of a rocket booster, n rounds up to 4
This is based on the core stage not igniting until the boosters burn out, by the way. With their current thrust levels, 4 Super Heavys trying to lift a 4 Super Heavy plus Starship/Super Heavy would have a TWR of 1.52, so it'd definitely be able to lift off under its own power.
To compensate for additional drag and gravity losses, perhaps 6 extra Super Heavy boosters (1.66 TWR at launch) would work better? If nothing else, it'd give it a good margin of error and spare fuel for boil-off during the flight to Mars.
Can you imagine a Starship Ultra Heavy, with 4/6 extra Super Heavys around the core? It'd either be the coolest thing ever or a humungous disaster waiting to happen.
